Liam is the breezy Irish short-form of William, and it carries the same sturdy meaning—“strong-willed protector”—but swaps the stately bow tie for a friendly hoodie. He slips off the tongue in one crisp beat (LEE-uhm) and, like a good Celtic fiddle tune, feels both classic and fresh. Hollywood has given the name a blockbuster shine—think Neeson’s steely resolve, Hemsworth’s easy grin, and Payne’s chart-topping croon—yet Liam still sounds like the boy next door who’ll share his crayons and stick up for a friend at recess. No wonder American parents have rocketed it to the very top of the popularity charts year after year. With roots deep in Gaelic soil and branches reaching into pop culture, Liam offers the best of both worlds: time-tested strength wrapped in modern charm, perfect for a little fellow destined to make big, kind waves.
